RFDump was first presented at the Blackhat Conference 2004
in Las Vegas (check out the slides from our presentation) and since then we have been striving
to turn this web site into a portal for information exchange regarding RFID technology. The intention is to provide
a forum where all people interested or concerned about RFID technolgy can discuss and exchange their
opinion in an open environment.

RFDump is a tool to detect RFID tags and show their meta information: Tag ID, tag type,
manufacturer etc. The user data of a tag can be displayed and modified using either a
Hex or an ASCII editor. In addition, the integrated cookie feature demonstrates how easy it is for
a company to abuse RFID technology to spy on their customers. RFDump works with the
ACG Multi-Tag Reader or similar card reader hardware.

Bruce Schneier about our work:

"[Grunwald] is doing what RFID is supposed to do," said security author and Counterpane Internet Security Inc. Chief Technology Officer Bruce Schneier. "This is serious. He didn't hack anything. RFID technology originally was designed to be completely open; that's its problem. He went to the spec, read it and followed it. If you query the chip, you will get this info. If there were security countermeasures on the chip that were thwarted, then we could talk about hacking."
